Those followers value the content so much that they sent Iron Road’s tweets to more than 130,000 a month.

Social media really proved its worth for Iron Road at an investor conference. After spending tens of thousands of dollars on flights and accommodation in Sydney for 3 executives plus conference fees, a disappointing number of investors attended the conference.

When Iron Road presented to the conference, only 120 investors were actually in the room. However, on LinkedIn, the presentation went to almost 5,000 people within a couple of days.

Iron Road completed an $11.5 million raising to begin acquiring land and funding its definitive feasibility study 6 months after it began its Twitter campaign. It has since raised another $40 million and $51 million is separate tranches.
